The effects of three different plant species on greenhouse gas emissions were investigated. Cyperus esculentus (Zone I), Typha latifolia (Zone II) and Phragmites australis (Zone III) were selected as the experimental species. Greenhouse gas emissions were sampled twelve times totally by using the closed chamber method between January and December. The highest level of emission was measured for nitrous oxide emission, released from Zone I in August (10,8371 kg CO2e/d). The lowest level of emission was measured for carbon dioxide emission (0,0156 kg CO2e/d) at Zone III in January. The results revealed that Cyperus esculentus has the highest greenhouse gas emission and the highest Global Warming Potential. All greenhouse gas emissions were influenced from different plant species. Phragmites australis could be used for minimizing the level of greenhouse gas emissions as it has the lowest level of greenhouse gas emission and Global Warming Potential. Finally, the possible level of greenhouse gas emission is estimated by using Monte Carlo simulation if the wetland is vegetated with only Phragmites australis. Approximately 33% of greenhouse gas emissions could be reduced if the wetland is vegetated only with Phragmites australis.","PeriodicalId":224531,"journal":{"name":"Turkish Journal of Water Science and Management","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132233042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the majority of diffuse pollutants arise from livestock breeding and agricultural activities, we focused to propose measures regarded with tackling the pollution from agricultural activities. The types and distribution of diffuse loads were expressed by total nitrogen and phosphorous parameters. We used the results of a yearlong surface water quality monitoring involving physico-chemical, chemical and biological parameters with specific pollutants and priority substances,set in the European Union Water Framework Directive as the AquaTool input data. The AquaTool model was run for attaining the outcomes of a series of measures determined according to the ecological sensitivity of each water body. The removal efficiency of pollution loads provided by the best management practices in agricultural activities and livestock breeding were compiled from literature,and typical removal rates were further determined for the basin. We produced nine alternative scenarios at first cycle for determining compliance measures for mitigating point and diffuse sources of pollution in surface water bodies, and water quality improvements observed in the Model were reported. A number of exemptions were defined for some of the water bodies that could not achieve the environmental objectives at the end of first implementation cycle. 759 proposed measures for tackling diffuse pollution were 81% of the total measures considered.

While observed meteorological data and river data sets were used for assessing changes in river systems and weather patterns, for future assessments, UK Climate Projections 2018 data was used. The studies in the literature have shown that during periods of extreme events, the river hydro-morphology is affected especially in terms of river flows, sediments and riparian zones such as draughts, and intense and heavy rainfall leading to reduced or exceptionally high flow respectively. Reduced flows can lead to the loss of habitat of aquatic organisms and an increase in fish deaths. Whilst increased river flows lead to changes of the hydro-morphology of rivers including changes to sediment dynamics and channels, rivers are also under negative effects of anthropogenic hydro-morphological pressures such as building dams and water abstractions. Furthermore, changes in river hydro-morphology can cause other problems such as increasing water temperature and decreasing dissolved oxygen, and thereby degrading Biological Quality Elements and Physico-Chemical Quality Elements. To deal with and mitigate these problems, a holistic view of water policy that considers climate change projections, reduces water demand, changes agricultural and urban land use practices, improves water availability and quality is required.","PeriodicalId":224531,"journal":{"name":"Turkish Journal of Water Science and Management","volume":"256 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122655118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The total amount of produced and distributed water was 14,184,650 m3 in 2018 for 79,296 people in Marmaris. Nonetheless, the volume of billed water was only 8,131,491 m3; therefore, the non-revenue water percent was 42.7% involving unbilled authorized consumption (5.1%), physical losses (28.9%), and administrative losses (8.7%). According to projections, water demand including the losses was 14,184,650 m3 in 2018, and is expected to increase to 22,204,429 m3 in the without-project scenario whereas it would reach 19,852,469 m3 in the with-project scenario by the year 2038. Consequently, five measures were proposed; establishing district metered areas and pressure management areas, infrastructure development, updating and extending Supervisory Control and Data Acquisition Systems, and other complementary measures to improve the efficiency of the water supply system. Applying the proposed actions would reduce the total water losses from 37.6% to 24.7% (19.9% physical, 4.8% administrative) in 2023, and the value would reach 20.3% (18% physical, 2.3% administrative) in 2038. This study presents that the proposed investment’s estimated total cost is € 2,956,739.26 and is foreseen to be implemented throughout 2021 and 2022. The Payback Period of the investment is 5.5 years (2027), and the Discounted Payback Period is 6.8 years (2028).

Benthic infauna, however, may respond to the pollution-induced spatial quality changes in a tidal inlet as they are incapable to avoid from the pollution sources and hence, from low quality of sediment and water. This research suggested that the interaction of sediment metal stressors and the possible associated factors finer grain fractions, estuary position and depth is likely to encounter with a specific distributional pattern of infauna. The communities of macroinfauna in Langstone Harbour were studied spatially from 36 samples collected across four subtidal stations, two each to the upper northern and the southern of the platform. The distinct variations in communities between and within stations and the most contributed species to variations were determined using multivariate analysis techniques. The structured model showed that the measured environmental factors explained 29.4% of infaunal community structure in the harbour with the highest contribution of chromium (6.6%). Environmental patterns suggested the increasing metal deposition in the finergrained muddy sediments towards the innermost basin with stagnant and shallower waters.","PeriodicalId":224531,"journal":{"name":"Turkish Journal of Water Science and Management","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121679946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The growth of cyanobacteria in dam lakes causes algae blooms and deteriorates water quality. Since it contains Methyl-Isoborneol, Geosmin and toxins, taste and odour problems in water occur and those threatens public health. Rising density of algae causes an increase in the total amount of organic carbon in water, which increases the amount of disinfection by-products.

The water samples were taken before and after the algaecide application, and total organic carbon, pH, chlorophyll-a, dissolved oxygen, copper, turbidity, orthophosphate phosphorus and total nitrogen were analysed. In order to calculate the amount and depth of the algaecide application, we determined which cyanobacterial species would be used. Copper ethanolomine is the main constituent of the algaecide so copper contamination in water has been investigated. In general, the density of cyanobacteria in bay and stagnant waters was increase before its application. According to the results of the study, appropriate doses and times are supporters to prevent algae blooms and to control sudden increases in the number of algae.

The virus, SARS-CoV-2 is spread by human to human transmission via droplets or direct contact. Although there is no evidence of its transmission from wastewater, the virus has been discovered in wastewater. Recent studies showed that SARS-CoV-2 is very sensitive to oxidants such as chlorine. Therefore, disinfection units of treatment plants need to be operated to avoid virus existence in the environment. Moreover, the disinfection process is vital if treated water is going to be used in irrigation. More than one-third of the effluents of wastewater treatment plants in Turkey reaches to agricultural irrigation facilities. The majority of these waste water treatment plants do not have a disinfection unit. Agricultural areas irrigated with treated wastewater have a rich crop pattern in Turkey. Almost half of these agricultural areas used to grow raw-consumable products. Therefore, disinfection units need to be operated properly and the facilities without disinfection unit should be revised. Moreover, regulations are not comprehensive to prevent public health in terms of reuse of wastewater in agriculture in Turkey. There are one regulation and one standard available considering reuse of wastewater in irrigation but neither of them is not covering indirect reuse of treated wastewater in the downstream. Therefore, to prevent public health it is needed to update regulations to include indirect reuse of wastewater.","PeriodicalId":224531,"journal":{"name":"Turkish Journal of Water Science and Management","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129923835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
